Risi Competizione at the 2017 24 Hours of Le Mans

Circuit de la Sarthe, Le Mans, France

June 4-17, 2017

Event Information

The 24 Hours of Le Mans (French: 24 Heures du Mans) is the world’s oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France. It is one of the most prestigious automobile races in the world and is often called the “Grand Prix of Endurance and Efficiency”. The event represents one leg of the Triple Crown of Motorsport; other events being the Indianapolis 500, and the Monaco Grand Prix. The race is organized by the Automobile Club de l’Ouest (ACO) and runs on the Circuit de la Sarthe, which contains a mix of closed public roads and a specialist racing circuit, in which racing teams have to balance speed with the cars’ ability to race for 24 hours without sustaining mechanical damage.

Since 2012, the 24 Hours of Le Mans has been a part of the FIA World Endurance Championship. In 2017, it will be the 3rd round of the season.

The race has over the years inspired imitating races all over the globe, popularizing the 24-hour format at places like Daytona, Nürburgring, Spa-Francorchamps, and Bathurst. The American Le Mans Series and Europe’s Le Mans Series of multi-event sports car championships were spun off from 24 Hours of Le Mans regulations. Other races include the Le Mans Classic, a race for historic Le Mans race cars of years past held on the Circuit de la Sarthe, a motorcycle version of the race which is held on the shortened Bugatti version of the same circuit, a kart race (24 Heures Karting), a truck race (24 Heures Camions), and a parody race 24 Hours of LeMons.

The Circuit

The circuit on which the 24 Hours of Le Mans is run is named the Circuit de la Sarthe, after the department that Le Mans is within. It consists of both permanent track and public roads that are temporarily closed for the race. Since 1923, the track has been extensively modified, mostly for safety reasons, and now is 13.629 km in length. Although it initially entered the town of Le Mans, the track was cut short in order to better protect spectators. This led to the creation of the Dunlop Curve and Tertre Rouge corners before rejoining the old circuit on the Mulsanne.

Another major change was on the Mulsanne itself in 1990, when the FIA decreed that it would no longer sanction any circuit that had a straight longer than 2 km. This led to the addition of two chicanes, reducing the time that the cars spent travelling at very high speeds on the old 6 km long straight. The addition of the chicanes was another safety precaution after the WM P88-Peugeot of French driver Roger Dorchy had been timed at 405 km/h (252 mph) during the 1988 race. Due to the shorter length of the straights, top speeds at Le Mans are now generally around 205 mph (330 km/h).

The public sections of the track differ from the permanent circuit, especially in comparison with the Bugatti Circuit which is inside the Circuit de la Sarthe. Due to heavy traffic in the area, the public roads are not as smooth or well kept. They also offer less grip because of the lack of soft-tyre rubber laid down from racing cars, though this only affects the first few laps of the race. The roads are closed only within a few hours of the practice sessions and the race, before being opened again almost as soon as the race is finished. Workers have to assemble and dismantle safety barriers every year for the public sections.
